Предельно короткие оптические импульсы в фотонном кристалле из углеродных нанотрубок под действием внешнего поля накачки

In this work, we considered the evolution of extremely short optical pulses in a photonic crystal of semiconductor carbon nanotubes placed in an external pumping field. The possibility of stable propagation of electromagnetic pulses under conditions of a pumping and damping field, due to the balance of dissipative forces and an external field, is shown. The stability of the shape of an extremely short optical pulse at long times is demonstrated with a change in various parameters of the medium, such as the period of inhomogeneity of carbon nanotubes in a photonic crystal and the modulation depth of the refractive index.

Three-dimensional diffraction-free Airy pulses in the medium of carbon nanotubes under the conditions of an optical resonator

Theoretically investigated the propagation of three-dimensional extremely short optical pulses, the longitudinal Airy cross section in a medium of semiconductor carbon nanotubes under the conditions of an optical resonator. Using numerical simulations, it was found that carbon nanotubes placed in an optical resonator create an environment in which the pulse propagates stably and conserves its energy, and also makes it possible to control some properties of an extremely short pulse (velocity and shape). The calculations of the pulse dynamics were carried out at long times, on the order of 100 ps.

Three-dimensional few-cycle optical Airy pulses in the array of carbon nanotubes with multilevel impurities

Propagation of few-cycle optical Airy pulse through the array of semiconductor carbon nanotubes (CNTs) is considered. CNTs are supposed to contain multilevel impurities. In our study, we have neglected transitions between the valence and the conduction bands. As a result, we have revealed the dependence of the pulse form on the parameters of energy.
